No, he generated "fake" Gameboy Camera images from the full color shots, by applying a crude form of dithering to graytone. I think that's perfectly reasonable.

What I'm saying is I would like to see comparison with a fourth image produced from the first (black and white) image by a batch Photoshop operation. I would guess a suitably tuned application of "brown tint, then selective Gaussian blur, then unsharp mask" would get you pretty close.
